    GJ 806 (TOI-4481): A bright nearby multi-planetary system with a transiting hot low-density super-Earth
    One of the main scientific goals of the TESS mission is the discovery of transiting small planets around the closest and brightest stars in the sky. Here, using...

    Global and Nonglobal Parameters of Horizontal-branch Morphology of Globular Clusters
    The horizontal-branch (HB) morphology of globular clusters (GCs) is mainly determined by metallicity. However, the fact that GCs with almost the same...

    Gradients of chemical abundances in the Milky Way from H II regions: distances derived from Gaia EDR3 parallaxes and temperature inhomogeneities
    We present a reassessment of the radial abundance gradients of He, C, N, O, Ne, S, Cl, and Ar in the Milky Way using the deep optical spectra of 42 H II regions...

    Gran Telescopio Canarias observations of an overdense region of Lyman α emitters at z = 6.5
    We present the results of our search near the end of the Reionization Epoch for faint galaxies. This has been done using very deep OSIRIS images obtained at the...

    Green, solventless debromination of C 70 Br 10 to C 70 with CsI
    A smooth, solventless and solid state debromination of C70Br10 can be achieved in a CsI matrix with the restoration of the pristine C70 in quantitative yields...

    GTC/CanariCam Mid-IR Imaging of the Fullerene-rich Planetary Nebula IC 418: Searching for the Spatial Distribution of Fullerene-like Molecules
    We present seeing-limited narrow-band mid-IR GTC/CanariCam images of the spatially extended fullerene-containing planetary nebula (PN) IC 418. The narrow-band...

    H II Regions Within a Compact High Velocity Cloud. A Nearly Starless Dwarf Galaxy?
    Within the SECCO survey we identified a candidate stellar counterpart to the Ultra Compact High Velocity Cloud (UCHVC) HVC274.68+74.70-123 that was suggested by...

    H α fluxes and extinction distances for planetary nebulae in the IPHAS survey of the northern galactic plane
    We report H α filter photometry for 197 Northern hemisphere planetary nebulae (PNe) obtained using imaging data from the IPHAS survey. H α+[N II] fluxes were...
